, IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 3,91 8, dated February20, 1845.

To all whom it may concern:

Be it known that I, EPHRAIM BALL, of Greentown, in the county of Starkand State of Ohi0,have invented certain new and useful Improvements inPlows and I do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the annexed drawings,making a partof thisspecification, in which Figure 1 is a geometrical elevation of thelandside of the plow; Fig. 2, an elevation of the opposite side of theplow; and Figs.3,4, 5, and 6, details.

Theintegral parts forming my plow are those generally found in otherplows-via, the beam A, the arms B, the landside (J, the colter D, thepoint E, the mold-board F, and the share G-notclaimihganyimprovementouthe beam, arms, mold-board, or share, and, as the same are of the usualshape and make, further description of them is superfluous.

The stock a of the landside rises from about midway of the top of saidlandside, when it immediately assumes a graceful curve in the directionof the plow-head. At its meeting with the under side of the beam avertical tenon, b, rises from it and passes through a correspondingmortise in the beam, on the top of which it is secured by a pin.

At the upper and forward extremity of 'the stock there is a sunknotch,c,for the reception of the upper corresponding end of the colter.

The lower and front part of the landside'is made in such a manner as toform a socket, d, of a corresponding shape to the hereinafterdescribedpoint E, to be inserted thereinto. On the under side of the landsidethere is the sole-piece e, which is furnished with ears or flangeslapping upon the inner side of the said landside, and by means of whichand screwbolts with sunk heads it is attached thereto.

The point E, in its general shape, resembles two arrow-heads, one oneach end of a common shaft. It is made of a square bar of iron,the upperand lower side of each end of which being made into a wedgeform foraboutone-third of the whole length, the remainder being reduced in such amanner as to form ashoulder, f, on top and bottom at the termination ofeach of the wedges. The middle part is also reduced the other way, butfor a greater length than the former-say about one-half of the whole length-formin g similar shoulders, g, on

A 1 he sides. A hole is drilled horizontally th rough the reduced partat or near each shoulder 91, through which screw-bolts pass into holesin the back of the socket d, by means of which the point is fastened tothe landside. The inclination of the point is at about an angle of aboutten degrees (more or less) with the horizon. The colter D is made of aplate of iron narrower at the top than at the bottom. The back edge,after leaving the beam for a short distance vertically, assumes a gentlecurve in a forward direction, then,reversin g the curve, turns backwarduntil it reaches the middle of the back shoulder, g, when it takes suchother (rectangular) turn as to fit said shoulder. The front edges, afterreceding from the beam,run parallel with the back edge to about.one-third the length of the colter. Then by a sudden curve toward thefront of the plow the colter increases to about double its width above,and the edge, continuing downward in a forwardlycurved directiomfinishesat thefront shoulder, g, of the point, fitting said shoulder. The upperend of the colter is fitted in the notch c and fastened by a screw-bolt.At the lower end of it there are two holes corresponding to those in thepoint and those in the socket of the landside, the same two boltsfastening the three parts together. Thus fastened together, greatstrength in the whole fabric is obtained, the colter, from its shape andposition,serving as a brace thereto.

The plow may be wholly constructed of cast or of wrought iron, or ofboth, its peculiar construction and arrangement being favorable to both.

Operation: The operation of the plow itself being so generally and wellunderstood, any comment thereon seems unnecessary in this place. Allthat need be said under theabove head maybe comprised in the followingfew lines. In consequence of the peculiar construction of the whole, orthe shape of the individual parts, each and any of said parts may easilybe detached in case of their wearing out or requiring sharpening, and aseasily attached again or replaced by others without disturbing the wholeor affecting the strength of the fabric. The point. being a double one,may point so that the three maybe secured together be turned around insuch a manner as to preby two bolts, giving at the same time great senta, new edge. strength to these, as hereinabove described. What I claimas my invention, and desire to E. BALL. secure by Letters Patent, is-Witnesses:

The manner in which I have combined the D. M. SEGHLER, colter, thelandside, and. the self-sharpening FRANCIS BENNE.
